Exam 3 - autonomic dysreflexia Flashcards
uncompensated cardiovascular reaction meditated by sympathetic nervous system; parasympathetic nervous system CAN NOT counteract these responses
autonomic dysreflexia
most common cause of autonomic dysreflexia
distended bladder or rectum
s/sx of autonomic dysreflexia
HTN (SBP up to 300)
throbbing HA
diaphoresis above level of injury
bradycardia (30-40 bpm)
autonomic dysreflexia will most likely occur with an injury above __
T6
autonomic dysreflexia process
stimulus occurs >
simulus sends nervous impulse to spinal cord >
reaches T6, norepi released >
norepi causes BP to rise >
BP rise signals brain >
brain compensates by slowing HR
what to do if autonomic dysreflexia is suspected
elevate HOB (sit upright)
notify HCP ASAP
assess, remove cause
–immediate cath, remove impaction, remove restrictive clothes, tight shoes
monitor + tx BP
pt, caregiver teaching
